Ancho is the dried form of a green poblano chile (if a poblano is ripened to a reddish colour, then dried, it is called a mulato). Anchos have a uniquely fruity raisin or prune flavour and fragrance. They are generally (but not always!) fairly mild, but packed with flavour. To prepare; wash, remove stem and seeds, toast very lightly (over-roasting will burn the chile and make it bitter) by tossing in a dry skillet until slightly puffed, then soak in hot water for about 20 minutes. Use anchos in soups, sauces, stews, rice and bean dishes, chile con carne, etc.
